I know that I have to change the computer and the knock sensor but is there anything else that I have to change.

I bought 24lb injectors

 

Just the chip, knock sensor (I don't use them on maf cars) and injs. 22lb is stock.
24s are ok, just make sure u swap it in the tune.

 

I am comparing the two at autozone.com and it looks like the egr valve is different and the electronic spark control module is different

do I have to change these or will it be ok

 

i just changed my car from 5.0 to 5.7, and learned the hard way that this stuff needed to be changed as i was told by the mechanic that is was all ok to still use in the 350, what im changing now is the chip, injectors, knock sensor and the ESCM (the egr valve as far as i know can be used for both)

 

so I replace the computer, injectors, knock sensor, escm and the chip. cool I dont want to just throw parts at the car but I want to replace what is nessesary

 

yeah and all that should be around $400 depending on where you get the injectors and parts thats how much i spent

 

Search feature is wonderful. Here is one. I'm guna go look at my 305 and 350 cars to see.
